His parents were Louis the Frank (1438–1471) and Mechthild, daughter of Count Louis I of Württemberg. On 17 February 1488 in Münden, he married Anna of Brunswick-Wolfenbüttel c. 1460 - Worms 16 May 1520], daughter of William IV, Duke of Brunswick-Wolfenbüttel and Elisabeth, Countess of Stolberg, with whom he had five daughters: * Mathilda, born in 1489 but died young. * Mathilda (born 1490; died 6 May 1558), married in Korbach on 19 May 1527 Konrad, Count of Tecklenburg (born 1493; died 16 August 1557) * Anna (born 1491; died 1513), a nun * Katherine (died 1525), married in 1511 Adam Count von Beichlingen (died Krayenberg 14 July 1538) * Elisabeth [10 September 1503 - Lauingen 4 January 1563], first married in Meisenheim on 16 October 1525 to Louis II, Count Palatine of Zweibrücken (born 1502; died 1532), later married on 9 January 1541 George, Count Palatine of Simmern (born 1518; died 1569).

After a pilgrimage to the Holy Land in 1491 where he was dubbed a Knight of the Holy Sepulchre, he probably contracted syphilis. He abdicated in favor of his brother William II on 3 June 1493, and spent the rest of his life in Spangenberg.
